“…Interestingly, there exist a variety of generalizations of A based on different symbolic data structures (Edelkamp and Reffel 1998;Hansen, Zhou, and Feng 2002;Speck, Geißer, and Mattmüller 2018a). In addition, multiple heuristics can be computed and represented with symbolic data structures, resulting in state-of-the-art heuristics for explicit heuristic search (Edelkamp 2002;Franco et al 2017;Moraru et al 2019). Thus, all the ingredients are present to allow a symbolic planner utilizing Copyright c 2020, Association for the Advancement of Artificial Intelligence (www.aaai.org).…”
